Genotype. — Dieucoila subopaca Ashmead. Monobasic. 



Head broader than thorax, longer than broad, eyes bare, cheeks 

 not margined,malar space less than half eye, antennae arising above 

 middle of eyes and facial outline in side view angled at this point, 

 13-segmented in female, 15-segmented in male with third excavated, 

 not longer than fourth and all flagellar segments cylindrical. Pro- 

 notum truncate. Mesoscutum without parapsides or carinae. 

 Scutellum not ending in a spine, cup well raised, narrow, tapering 

 gradually into a prominent median carina which separates the two 

 large pits at base, axillae prominent but not ending in distinct teeth, 

 disk alveolate, rounded or crenate behind. Front wing normal in 

 shape and size, pubescent and ciliate, radial cell closed. Abdomen 

 with hairy ring at base, only normally compressed. 



Among the characters used by Ashmead to distinguish this genus 

 was the peculiarity of the dull and sculptured head and thorax and 

 this character alone has been used by Dalla Torre and Kieffer to 

 separate it from all the rest of the Eucoilinae. The H. H. Smith 

 South American collection also contained representatives of two 

 other species with the habitus and other generic characters of this 

 genus, and from them it is seen that the above mentioned sculpture is 

 merely a specific character although both show traces of it on the 

 head. The lack of a club in female antennae is evidently a specific 

 character also. The genus is closely related to Miteucoela Kieffer 

 whose genotype has a five segmented club and a body without sculp- 

 ture. It is separated from Aglaotomidea Rohwer and Fagan by the 

 lack of an abnormally long third antennal segment in the male.
